This change is the main check in for the historical app op feature.
The idea is to store a historical data about past app op rejections,
accesses, and durations per op for any UID state indefinitely.
Keeping all operations on record is not practical as app ops are
very frequently performed. To address this we are storing aggregated
data as snapshots where we store for every UID and its packages
how many times each op was accessed, rejected, lasted as an aggregate.
To allow history scaling indefinitely we are taking a logarithmic
approach with only the most recent state stored in memory and all
preceding state stored on disk. State on disk is stored in separate
files where each preceding file, i.e. for an older period, would
cover X times longer period with X number of snapshots covering
X times longer period. Initially X is ten but can be tweaked. For
example, the first file could contain data for ten days with daily
snapshots, while the file for older period would have data
for a hundred days with snapshots every ten days, etc.
The implementation is optimized for fast history update and no impact
on system runtime performance and minimizing memory footprint. We
are lazily persisting state to disk on a dedicated thread as this is
slow. We are also reading the relevant historical files on a query
as this is very rare as opposed to state updates.
The base snapshot interval, i.e. snapshot time span, in the initial
iteration and the logarithmic step are configurable. These can be
changed dynamically and the history would be rewriten to take this
into account.

The API is mostly implemented; except for hooking up the listener
and handling an already running bugreport.
BugreportManager is the handle to the new API exposed to apps.
Generating bugreports requires root privileges. To limit the footprint
of the root access, the actual bugreport generation in Dumpstate binary,
is accessed as a oneshot service and dies after it finishes
running.
System server accesses Dumpstate via a binder interface since it does
not have root privileges.
Starting a oneshot service is done via setting a system property, which
needs to be done from system server. BugreportManagerService is the
new system server service that does this. BugreportManager calls into
BugreportManagerService via a binder interface, since the former is in
the app's process.
Both app to system server as well as system server to native service
calls are via implementations of IDumpstate binder interface.

Introduce a new range of app-zygote isolated UIDs, [90000..98999].
For each app that uses an application Zygote, allocate a range of
100 isolated UIDs. The application Zygote for an app will get a
UID out of that range, and all other children that are forked
from that zygote will get a UID from the same range.
Bug: 111434506
Test: app Zygote and its children run in the new range of
isolated UIDs (with SELinux disabled). New set of
tests for UID allocators pass.

When an application has requested isolated services to be spawned
from an app zygote, we need to spawn the app zygote itself, and then
ask it to fork an isolated service.
The application zygote currently only creates the class loader, and
doesn't do much else. We keep track of the isolated services that
use the app zygote, and when the last isolated service goes away,
we stop the app zygote itself (after a timeout).
The app zygote itself runs with the app's UID and under the app
seccomp filter. That last one is too restricted, so this currently
only works with SELinux disabled.
Future CLs will add an application callback for preloading.
Test: start multiple isolated services with useAppZygote="true",
verify app_zygote starts, services start as a child of
app_zygote. Stopping all services stops app_zygote as well.

The new isolated storage model we're building in Q introduces new
strongly-typed media permissions which replace the broad "Storage"
runtime permission.
That legacy "Storage" permission is marked as being "removed", and
it also splits into the new media permissions, but apps are confused
when they request the "Storage" permission, which no longer appears
as granted when the user accepts the new split media permissions.
After discussing with the permissions team, the best short-term
solution is to add special-case logic that grants the legacy
permissions when *any* of the new media permissions have also been
granted. Only when the user revokes *all* of the new media
permissions is the legacy permission then revoked. (MediaProvider
is already internally filtering the relevant content based on what
new media permissions the caller holds.)

If a session is marked as isStaged, write the package files directly on
a directory named /data/staging/session_${SESSION_ID}, instead of the
/data/app temporary directory. This allows us to set different SELinux
policy (e.g. allowing apexd to read that directory), and to persist the
data across reboots without altering the existing code.
To ensure we cover existing workflows, in this CL we try as much as
possible to re-use existing code to create staging directories and wire
data into them.
Bug: 118865310
Test: Verified that adb install --staged file.apk successfully creates a
/data/staging/session_SESSION_ID/base.apk file. If --apex is passed, the
file is named base.apex.

Members modified herein are suspected to be false positives: i.e. things
that were added to the greylist in P, but subsequent data analysis
suggests that they are not, in fact, used after all.
Add a maxTargetSdk=P to these APIs. This is lower-risk that simply
removing these things from the greylist, as none of out data sources are
perfect nor complete.
For APIs that are not supported yet by annotations, move them to
hiddenapi-greylist-max-p.txt instead which has the same effect.

For apps which target Q or above, add the O_CLOEXEC flags to
ParcelFileDescriptors.
O_CLOEXEC is essential for ensuring that file descriptors do not leak
across an exec() boundary. Setting O_CLOEXEC ensures that file
descriptors can't linger around unnecessarily in an exec()ed process
which doesn't use them, making more efficient use of resources.
Additionally, O_CLOEXEC is important in ensuring that untrusted
exec()ed code cannot take advantage of leaked file descriptors.
